IP组播视频会议系统用户端控制的设计与研究

The Research and Design of User-end Controlling Based on IP Multicast Video Conference System

提出一种采用PC机与视频采集设备,以VC++ 6.0为开发平台及相应的网络技术构建的纯软件视频会议系统设计方案,并利用IP组播技术实现视频会议系统中视音频数据流的通信。由于组播协议并没有提供认证支持,无法实现对组播成员的管理,重点对用户端控制的方案作了深入研究与分析。

The paper designs the video conference system by using the personal computer, video capturing device, network technology. The system is based on Visual C＋＋ 6.0 developing platform. The transmission of the video and audio data uses IP muhicast technology. Because multicast protocol lacks in the certification that can not administer multicast members, the paper concentrates on the research and analysis on the user - end controlling which is realized in the design.
